...Kandang Kerbau Hospital, all found themselves reaching back to studies of ducks and seals-experiments that were in some cases nearly a century old. When those aquatic creatures swim below the surface, a "dive" reflex slows their heartbeats and contracts their peripheral arteries, thus concentrating the available oxygenated blood in the heart and brain. Most of the body's tissues then switch from an oxygen-burning system to one in which nutrients are "burned" without oxygen...
...Pediatrics, the seven medical researchers suggest that this same reflex may be what causes many premature and some full-term infants to shut down the flow of blood through their lungs. Some unborn infants may have had the reflex activated to compensate for an oxygen shortage caused by low blood pressure in the mother, or a constriction or partial separation of the umbilical cord. As a result, the babies are born with thousands of constricted arterioles that do not carry sufficient blood to the lung's air spaces where oxygen is picked up-a condition that leads...
...physical checkup, thieves broke into his parked Lincoln Continental and found the secret button inside the glove compartment that unlocked the trunk. Though they left several suitcases of clothes, they heisted the car's spare tire, a $170 portable radio, a $10 box of candy, and the oxygen kit Ike uses when he gets short of breath...

The ultraviolet light from the sun that freely penetrates the thin Martian atmosphere would probably kill earthly plants and animals, but Martian life may have found some means to protect itself...
